The geothermal energy
Geothermal energy is a renewable energy source because the heat is continuously produced inside the earth.
If the rocks aren't hot enough to produce steam we can sometimes still use the energy - the Civic Centre in Southampton, England, is partly heated this way as part of a district heating scheme with thousands of customers.
The geothermal gets its power throw hot rocks underground heat water to produce steam.
We drill holes down to the hot region steam comes up, is purified and used to drive turbines, which drive electric generators.
These energy don’t contaminate the environment is very clean.
It is use in United States, New Zealand, Iceland, Japan and the Philippines.
